A hairbrush is provided. The hairbrush includes a handle with an engagement shaft featuring a first magnet, a brush head with a first end and a second end, and bristles radially distributed around the brush head body. The hairbrush further includes a second magnet disposed within a receiving volume of the brush head. The first magnet attaches to the second magnet. The resistance to rotation of the brush head with respect to the engagement shaft is achieved through the magnetic interaction between the first and second magnets. The brush head rotates upon encountering resistance from tangled or matted hair, allowing it to brush past the tangled or matted hair and limit the maximum amount of tension that would otherwise be transferred to the hair.

The present invention provides a mechanically-actuated livestock brush apparatus, for tending to animal livestock, whose movement can be actuated and also controlled via a mechanical means. In an embodiment, the mechanical means may include a spring device. The mechanical means should be such that it provides sufficient resistance for a controlled movement of the brush apparatus preventing infinite movement, e.g., infinitely rotating/revolving, while also provides sufficient resistance such that when an animal pushes against it, it does not move freely or randomly, but puts resistive pressure against the animal's body for a good scratch. Also, the brush apparatus has a universal motion, allowing it to move in multiple directions.
